"Straight after the show he came up to us and said sorry for what happened," Adam told Digital Spy. "We felt more sorry for him - he was the one who was hit! It could have been anything."

Asked if they considered including an egg-themed song on their debut album The Impossible Dream - which includes highlights of their performances from the series - Richard confessed: "We've never given it a thought! To be honest, I don't eat eggs anymore. I've cut them out [of] my diet... I've been traumatised!"

The pair also revealed that Cowell has yet to hear their LP, adding: "Hopefully he likes it. We'll wait to speak to him and let you know!

"We briefly spoke to all the judges after the show - they were so supportive and told us to work hard. We haven't seen them since, but we'd love to get their thoughts on the album."
